仿快捷酒店滑動選擇calendar控制元件（使用HitRect）
阿新 • • 發佈：2019-02-09
宣告：大神勿噴！！
今天我給大家講個故事：
long long ago...山裡有個公司，公司裡有個產品經理在給程式設計師講需求，需求是這樣講的：我要一個仿製快捷酒店的Calendar控制元件！！！（UI設計師在旁邊陰暗的冷笑）...
好了言歸正傳，上一篇的的HitTest讓我懂了一些基本的東西，在這裡總結下：
HitTest：
在父View抓取當前touch的X，Y座標（相對於父View）。然後與子View挨個比對，看看父View的觸點是否在子View相對於父View的範圍內。
這樣我們就能輕鬆的解決一些下面的Calenadr;
上程式碼：
